Hi Grant, On FreeBSD, Webmin uses the command ping -c 1 -t 1 192.168.0.7 to check the host, and then looks at it's exit status. If it is exiting with status 0 (meaning OK) even when the host is down, then this is a problem .. - Jamie On Tue, 2006-03-07 at 06:39, Grant Peel wrote: > I suppose the next time the server to be monitored goes down, I can try > pinging it and sending you the output, but I hope it does not happen! > > Here is the ping results from the server running the ping command to the > server to be monitored, from the command line of course. > > Yes, FreeBSD 5.4 > > defiant# ping -c 1 192.168.0.7 > PING 192.168.0.7 (192.168.0.7): 56 data bytes > 64 bytes from 192.168.0.7: icmp_seq=0 ttl=64 time=0.325 ms > > --- 192.168.0.7 ping statistics --- > 1 packets transmitted, 1 packets received, 0% packet loss > round-trip min/avg/max/stddev = 0.325/0.325/0.325/0.000 ms > defiant# > > -GRant > > ----- Original Message ----- > From: "Jamie Cameron" <jca...@we...> > To: <web...@li...> > Sent: Monday, March 06, 2006 7:13 AM > Subject: Re: [webmin-l] Host Is Down > > > > Webmin doesn't actually use the output from the ping command - instead, > > it either checks the exit status of the ping command (0 for success or 1 > > for failure), or sends its own UDP ping packets. > > > > By the way, which OS are you using there?
